Canopy cleaning for sites in City of London

How we handle canopy cleaning in City of London

For canopies and hoods in City of London, the work follows the same careful routine: we remove the filters, clean the plenum and housing, then degrease the canopy shell. Before and after pictures go into your report. Common call-outs are for poor capture at the hood and wet, greasy drips from the hood, across wall canopies, island canopies and canopy light fittings.

In a London area like City of London, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, so a regular TR19® clean protects everyone in it.

The paperwork matters as much as the work. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

What the work involves, part by part

Island canopies

The underside of an island canopy is in full view so a clean, even finish matters. It’s degreased and photographed for your report.

Grease troughs and gutters

Some troughs drain to a cup or drawer, that’s emptied and cleaned too, and we’ll show staff where it is.

Grease, kitchens and City of London

The FSA’s food hygiene register shows about 3,230 restaurants, cafés and canteens and about 953 takeaways and sandwich shops within about 1.5 miles of central City of London. Each canopy in those kitchens catches grease on the inside of the hood and behind the filters. Overnight is the normal time to clean a London kitchen extract, so trading is not affected. City of London sits within the area of London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.

Volunteers running a hall kitchen near St Olave Old Jewry, or anywhere in City of London, may not know when the extract was last cleaned, and a grease test settles it. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to City of London is London Bridge Hospital, about 0.6 miles south-east.

City of London is about 1 mile north of London, in City of London. City of London gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where needed and a written report with photos.

All of EC4V, EC1A, EC2M and EC2Y is covered for canopy cleaning, from the main roads to the quietest streets. That includes premises on Aldermanbury Square, Monkwell Square and Paternoster Square and nearby roads. Being close to the A1 and A3, City of London is easy for our technicians to reach for canopy cleaning. We also cover the places around City of London: Barbican Estate (1 mile north), Bishopsgate (1 mile east), Finsbury (1 mile north), Aldgate (1 mile east) and St Luke's (1 mile north).

City of London: your questions answered

Which environmental health team covers City of London?

The local authority for City of London is the City of London Corporation, and its environmental health team does the inspecting. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.

Which fire service covers City of London?

Fire safety enforcement in City of London is handled by London Fire Brigade. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.

Does a canopy clean meet TR19?

Canopy cleaning is part of TR19, not the whole of it. Your report lists exactly what was cleaned, so your records stay accurate.

How much notice should we give?

It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.

What happens to the filters during the clean?

The filters come out so the plenum behind them can be cleaned, and they’re cleaned before going back in. Any that are damaged are noted on the report.

What kinds of canopies do you clean?

Most commercial kitchen canopies, from one small hood to a long run of canopies. We work out the approach when we survey, from photos or a visit.

Do you look at the system first?

Yes. We always survey first, either from photos and details you send or on a site visit. A fixed quote follows.

Do you have insurance?

Yes, we’re fully insured. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.

How we price canopy cleaning

We quote each job individually. This is what makes a difference:

  • Parking and loading at the site
  • How many systems or sites are involved
  • The times the site is available
  • The condition we find in the survey

The cost depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.

Asking for a quote

What to send for a quote:

  • Any access panels or hatches you can see
  • How we’d reach plant on a roof or in a plant room
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • A few general shots of the system

Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Managing agents and facilities teams in City of London

Facilities teams in offices, schools and healthcare sites book us too across City of London. Larger estates can be phased building by building to keep disruption down.

Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.

How the visit works

Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes an hour or two for one small canopy, longer where there are several. Before any visit in City of London, we agree where the van can stop and how equipment reaches the system.

  1. We start by checking the canopy and what’s behind its filters.
  2. Equipment is turned off and cooled, and the area under the canopy is protected.
  3. Heavy deposits come off by hand, then the surfaces are degreased.
  4. Plenum, housing, troughs and canopy are all cleaned and checked.
  5. You get pictures of the result and a recommended date for the next clean.

How to prepare

  • Mention any sign-in, permit or induction we need
  • Arrange a key holder or contact on site
  • Mention any locked doors, roof access or ceiling voids

How to get a quote

Getting a quote doesn’t take long. Send a few details and photos, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

Advice

What we are called out for in City of London

Most canopies have troughs or channels that catch running grease. Left to fill up, they spill over, and grease ends up dripping from the canopy edge.

Most sites get in touch after spotting something like this:

  • Greasy streaks across the canopy
  • Wet, greasy drips from the hood
  • Smoke hanging around the canopy during service
  • A plenum thick with grease behind the filters

School kitchens, at schools like Fashion Retail Academy for example, are typically cleaned in the holidays so no lunches are lost.

What your quote should include

  • Proof of insurance
  • Whether the work can be done while the site is closed
  • Whether the whole system is included, or only the parts that are easy to reach
  • Which accreditations they hold, and whether you can check them

Questions to ask before you book

Looking after it afterwards

Here’s the after-treatment advice, short and simple:

  • Check filters are not leaving gaps
  • Clean the hood’s outer surfaces daily
  • Wash or exchange the filters on a regular cycle
  • Use non-abrasive cloths on the hood

A full system clean comes with a TR19 certificate from the BESCA Vent Hygiene Elite portal. Where only the canopy is done, the report says so clearly.

Run the extract for as long as anything is cooking. Turning the fan off early lets vapour settle on the hood.

What canopy cleaning can’t fix

In fairness, there are a few things this work won’t fix:

  • Ductwork and fans beyond the canopy (those need a full TR19 clean)
  • A fan that can’t pull enough air because it’s worn out
  • Bent or broken filters

Not sure which it is? You can ring 0345 646 2711 or drop us a line and we will tell you honestly before you book.
